Writing a Narrative composition appeals to one of humankind's basic instincts, the impulse to share stories. Sometimes the aim of the story-teller is simply to entertain, to provide a moment of escape from the business of the day or the horrors of the night, but sometimes the aim of the story-teller is to instruct, to help others in their understanding of something. The best part of teaching in this way is that our listeners' natural resistance to heeding the words of others is low and they are not always aware that they are being taught anything until it's too late we've got them.
The skills needed to narrate a story well are not entirely the same as the skills needed to write a good essay. Some wonderful short fiction writers are not particularly good essayists and vice versa. Still, it is useful to look at those elements that make up a good narrative and know how to apply what we learn toward making our essays as dramatic as possible whenever that is appropriate.
